Installation 5 RACK MOUNTING – Adequate ventilation is very important in multichannel installations. Units should be spaced apart by at least one panel height wherever possible, and some air movement is advisable in enclosed rack cabinets. Excessive heat will shorten component life and unit performance will be degraded without proper cooling. CONNECTIONS AND CONTROLS – All connections to and from the HCP2550A are made through the rear panel.
